I am considering using a donor C4 corvette engine and transmission or small block 350 crate engine. What are advantages and disadvantages. | | |

Advantages to a v8 would be power and speed, but you knew that.
Disadvantages will be fuel mileage, depending on how you drive, and all the work and money it takes to pull off a conversion.
I think another disadvantage of a v8 in an AD is that everyone has one, it's a "belly button engine" as they say.
Personally I don't look very hard at an AD with a v8 when I see them in truck shows.
Consider what you want to do with your truck, then think about engines.
I suggest a 261 or something completely different, like a diesel.
What size truck do you have?

I have the original 228 that runs ok but it is not something I want to keep. I am just doing some planning and I do not want to have to change the firewall to accomadate a larger engine. | | |
